There are other ways, easier? no.
The 'show new replies to your post' button will bring up thread in which you participated that have new replies.... no searching required.
For threads in which you aren't participating but know the title of:
-Open the board they are in
-Click on the word subject in the column header (this will make them all in alphabetical order)
-then click on the pages until you find your thread. Note the number of the page as it will be close to the one you need the next time...
Or.... you can just bookmark the pages you want to track and then click on the Bookmarks button in the menu. Like BiMi said, a 'new' sign will appear in the ones that have new posts. It really isn't alot of work. You only have to click the 'bookmark' in each thread you want to track once.
If this doesn't suit you... you can always link the threads in your o/o thread you are allowed or even bookmark them in your web browser.
don't you love choices?
Edited to add: you can also click the 'notify' button in each thread. That way when a new post is make you will receive an email. Then you can just click the link in the email and it will open a browser page to the thread.
I also love the choice of not wasting thread space on an OOC thread when we all use Skype to talk about OOC stuff.
Really no hard feelings I already knew about most of the ways you guys are telling me about to find a thread. I was simply asking if there's another search function I don't know about or if there's any plans to refine the search function a bit.
And from the answers I'm getting the answer to both those questions is a resounding NO.
Thanks for the talking down to though, I love being talked to like I've never used a web browser before.
